This invention relates to a gauge for use in the placement of posts and like, and particularly to insure the prop along a highway.

In erecting guard-posts, it is desirable that they be vertical and located a uniform distance from the margin of the roadway.

The erection gauge of this invention constitutes a simple, accurate, economical, and easily usable means for so setting the posts that they are placed at a uniform predetermined distance from the roadway margin and with their tops at a predetermined height above the roadway surface.

The invention also provides a gauge that is adjustable and usable conveniently to insure the vertical placement of the posts at tance from the roadway margin where grades on the berme are due to super-elevation on curves.

When considered with the description herein, characteristics of the invention are apparent in the accompanying drawing, forming part hereof, wherein embodiments of the invention are disclosed for purpose of illustration.

Like reference-characters refer to corresponding parts in the views of the drawing, of which- Fig. 1 is a plan view, in position against a post;

Fig. 2 is a side elevation of the gauge and a post, together with a fragmental cross section of a roadway and ground adjacent thereto;

Fig. 3 is a plan view of the lower. part of the gauge, the posts and parts of the gauge being shown in section on the line 3--3, Fig. 2;

Fig. 4 is a side elevation of a modification.

In the drawing, A designates the roadway or paved surface of the highway, B ground at a side of the roadway, and C a guard-post.

For economy of manufacture and convenience of use, the principal members of the gauge usually are of angle iron as shown.

Referring to Figs. 1, 2, and 3, a base-bar of the gauge, which is horizontal or approximately so when the gauge is in use, is formed of two lapping members 5 and 6, which are relatively slidable for adjustment of the length of the bar. Each of these members has a longitudinal series of equally-spaced holes I, which accommodate bolts 8 that hold the members together at the desired length of the base.

A transverse foot member 9 is secured to the lower surface of the base member 5 near one end thereof at right angle thereto. The foot member is adapted to abut and lie substantially parallel er positioning of guard-posts a uniform disthe gauge being shown to the margin of the 5-0 contacts with roadway. The foot member may be long to. cause the base-bar to assume position perpendicular to the The .other'base member s PATENT. OFFICE roadway A when the part of the base member therebeyond (designated by the upper surface of the sufficiently roadway margin.

6 has secured thereto near its free end a foot member l0 that extends laterally therefrom so the post when the pa that it may contactwith' rt of that base member 10 therebeyond (designated by' 6-a) also contacts the post.

An upright member ll perpendicular to the base-bar is connecte therefrom.

allel to the base for post directly above the The extension l3 has a the same distance from lower foot member ill for Thus, when the post d rigidly to member 6 at or near the foot member Ill and extends upwardly I2 extends from the base l2 in its upper portion is l3 that is connected contact with a side of the base member part 6-0.. foot l4 fixed thereto at the upright H as the contact with the post. contacts the two feet, it is parallel with the member I I.

A double level I5 is extension l3 and the foot in which the post sets.

The base of the gauge is fixed in the angle of the M opposite to the angle adjusted, by relative sliding of its members 5 and 6, to set the foot I members 9 and II] the distance apart corresponding to the distance from the roadway is desired to position margin it the guard-posts, and they 5 are held in that adjustment by the bolts 8.

When the base is placed with its foot member 9 against the margin set is placed against H! and against the base of the roadway, a post to be the feet members In and member 6 and the ex- 40 tension 13. The gauge is held with its base horizontal, and its upright dicated by the level from the roadway.

When the gauge is posts with their tops the roadway surface,

dinarily is of the same its upper surface lies in plane as the upper ll thus is vertical, as inl5, and consequently the post is vertical and at the pre determined distance to be used for the setting of a uniform distance above the'upright member II orlength as that distance cc of the base of the gauge. 'post has been driven until the same horizontal end of the upright member,

its upper end is at the desired height. However,

the upper end of th e upright member maybe provided with a scale I 6,. to indicate lower desired positions of the upper ends of posts when it is desired to erect them of less height above the roadway surface.

Sometimes it is necessary, owing to various grades on the berme due to super-elevations on curves, to have adjustment in the gauge that will permit the base thereof to slant from the roadway surface below the horizontal, and at the same time to permit adjustment of the upright member I I to the true vertical and its maintenance'in that position.

A gauge for use in these circumstances is exemplified by Fig. 4. As there shown, the base member B is connected pivotally to the upright member II as indicated at ber l2 similarly is connected to the upright member II as indicated at I8.

When it is necessary or desirable to deflect'the base of the gauge from the horizontaLthe' pivots permit the upright member II to be adjusted to the vertical as indicated by the level I5. The base member and themember I2 then are in such positions as shown by dotted lines in Fig. 4.

With this gauge, guard-posts 'maybe set rapidly and accurately along a roadway. The gauge being held with the foot member 9 against the roadway margin and with. its base kept horizontal, it is easy to place a post in the angles afforded by the base part 6-a and the foot member") and the extension I3 and the foot member I4, and thus the post is in vertical position. Guard I1, and the diagonal memanother abutment on said bar to contact a structure away from which the work is to be positioned.

2. A gauge comprising a base bar, an abutment on and extending laterally from said bar between the ends of the latter affording a lower angle with an end portion thereof into which work may be set, an upright member carried by said bar, a diagonal brace extending from said bar connected to said upright member and having an upper terminal portion extending beyond said member and disposed in alinement with said bar, an abutment carried by said upright member aifording an upper angle with the upper terminal portion of said brace in alinement with the lower angle into which Work may be set, and another abutment on said bar spaced from the lower angle to contact a structure away from which the work is to be positioned.
